What Is Polytar Scalp Shampoo and How Does It Help?

 

If you've been dealing with a persistently flaky, itchy, or inflamed scalp, you'll know how frustrating it can be. Polytar scalp shampoo is a medicated, over-the-counter treatment containing coal tar solution 4% — a well-established active ingredient used for decades in the management of scalp psoriasis, dandruff, and seborrhoeic dermatitis. It's not a cosmetic shampoo. It's a licensed medicine, and that distinction matters. You can browse our full range of hair care products if you're looking for complementary options alongside your treatment.

Scalp psoriasis affects roughly 50% of people who have psoriasis, according to NHS guidance, and it can significantly impact quality of life. Polytar has been a trusted name in medicated scalp care for many years, offering a straightforward, accessible option for people who want to manage their symptoms without a prescription.

 

How Does Polytar Scalp Shampoo Work on the Scalp?

 

Coal tar works through several mechanisms that together help calm an overactive scalp. It's not entirely understood why psoriasis causes skin cells to multiply so rapidly, but coal tar helps to slow that process down. Here's what it does:

  • Slows down the excessive proliferation of keratinocytes (skin cells) on the scalp surface
  • Reduces inflammation and redness associated with psoriasis and seborrhoeic dermatitis
  • Relieves itching by acting on nerve endings in the skin
  • Has mild antifungal properties, which may help address the Malassezia yeast linked to dandruff

The result? Fewer flakes, less itch, and a calmer scalp over time. It won't work overnight — consistency is key — but many people notice a meaningful improvement within a few weeks of regular use.

 

Who Should Use Polytar Scalp Shampoo?

 

This shampoo is suitable for adults and children over 12 years of age who are experiencing scalp conditions that haven't responded well to standard cosmetic shampoos. It's particularly useful for:

  • People with diagnosed scalp psoriasis looking for an OTC maintenance option
  • Those with persistent dandruff or seborrhoeic dermatitis of the scalp
  • Individuals with itchy, flaky scalp conditions not caused by a fungal infection requiring prescription treatment
  • Adults who want a medicated option they can use regularly without visiting a GP

It is not suitable for children under 12 without medical supervision, and you should avoid using it on broken, infected, or acutely inflamed skin. If you're unsure whether this product is right for your condition, speak to a pharmacist before purchasing.

Antifungal action Mild Strong (azole antifungal)
Anti-proliferative action Yes — slows skin cell turnover No
OTC availability in UK Yes Yes (2% strength)

 

Is Polytar Scalp Shampoo Suitable for Sensitive Scalps and How Should It Be Stored?

 

If you have a sensitive scalp, it's worth doing a small patch test before using Polytar scalp shampoo for the first time. Apply a small amount to the inner forearm, leave for 24 hours, and check for any reaction. Coal tar can occasionally cause mild irritation, particularly on very sensitive skin. It can also temporarily increase your skin's sensitivity to sunlight — so if you're spending time outdoors after use, protect your scalp with a hat or appropriate sun protection.

Store the shampoo below 25°C, away from direct sunlight, and keep it out of reach of children. Do not use after the expiry date printed on the bottle. If you're managing a broader skin condition alongside your scalp symptoms, you might also find our skin care range helpful for body-area psoriasis or eczema.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

Specifications of Polytar Scalp Shampoo

 

What Is Polytar Scalp Shampoo and What Is It Used For?

 

Polytar Scalp Shampoo is a medicated topical treatment containing coal tar solution 4% as its active ingredient. It is used to treat a range of chronic scalp conditions, including scalp psoriasis, dandruff, and seborrhoeic dermatitis. These conditions share common features — flaking, itching, and inflammation — but they have different underlying causes. Coal tar has been used medicinally for over a century and remains a recognised treatment option in UK clinical practice for these conditions.

Psoriasis is a long-term skin condition where the immune system speeds up skin cell production, causing cells to build up on the surface. On the scalp, this leads to thick, scaly patches that can be itchy and uncomfortable. Dandruff and seborrhoeic dermatitis, while related, are often linked to an overgrowth of the Malassezia yeast on the scalp. Polytar Scalp Shampoo addresses both the inflammatory and proliferative aspects of these conditions.

 

What Do You Need to Know Before Using Polytar Scalp Shampoo?

 

Before using this shampoo, read the following carefully. There are certain situations where you should not use this product, or where you should seek advice first.

Do not use Polytar Scalp Shampoo if you:

  • Are allergic to coal tar or any other ingredient in the formulation
  • Have acutely inflamed, broken, or infected skin on the scalp
  • Are under 12 years of age (unless directed by a doctor)
  • Have folliculitis (infected hair follicles) on the scalp

Speak to your doctor or pharmacist before use if you:

  • Are pregnant or breastfeeding — safety data for coal tar in pregnancy is limited
  • Have a history of skin cancer or are at high risk of skin cancer
  • Are using other topical scalp treatments at the same time
  • Have very fair or sensitive skin that burns easily in sunlight

Drug interactions:

  • No significant systemic drug interactions are known for topical coal tar at this concentration
  • Avoid using alongside other photosensitising topical agents on the same area

 

How Should You Use Polytar Scalp Shampoo Correctly?

 

Using this shampoo correctly makes a real difference to how well it works. Follow these steps each time you wash your hair with it:

  1. Wet your hair and scalp thoroughly with warm water
  2. Apply a sufficient amount of shampoo directly to the scalp
  3. Massage gently into the scalp using your fingertips — avoid vigorous rubbing
  4. Leave the shampoo on the scalp for 3 to 5 minutes to allow the coal tar to work
  5. Rinse thoroughly with warm water
  6. Repeat the application if needed, then rinse again
  7. Avoid contact with eyes — if contact occurs, rinse immediately with plenty of water
Indication Age Group Dose Frequency
Scalp psoriasis Adults and children over 12 Sufficient amount to lather scalp 2–3 times per week
Dandruff / seborrhoeic dermatitis Adults and children over 12 Sufficient amount to lather scalp 2–3 times per week
Maintenance (symptom control) Adults Sufficient amount to lather scalp Once weekly or as directed

If you're also managing hair thinning or loss alongside your scalp condition, you may find it useful to explore our female hair loss range for additional support options.

 

What Are the Possible Side Effects of Polytar Scalp Shampoo?

 

Like all medicines, Polytar Scalp Shampoo can cause side effects, although not everyone experiences them. Most side effects are mild and localised to the scalp.

Common side effects:

  • Mild scalp irritation or stinging on first use
  • Temporary redness of the scalp
  • Slight dryness of the hair or scalp
  • Temporary discolouration of light-coloured or chemically treated hair

Less common side effects:

  • Increased sensitivity of the scalp to sunlight (photosensitivity)
  • Folliculitis (inflammation of hair follicles) — stop use and seek advice if this occurs
  • Allergic contact dermatitis — characterised by worsening redness, swelling, or blistering

If you experience any severe or unexpected reaction, stop using the shampoo immediately and contact your pharmacist or GP. Do not ignore a worsening rash or signs of an allergic reaction.

 

How Should You Store Polytar Scalp Shampoo?

 

Correct storage helps maintain the product's effectiveness and safety throughout its shelf life.

  • Store below 25°C in a cool, dry place
  • Keep away from direct sunlight and heat sources
  • Keep the bottle tightly closed when not in use
  • Store out of sight and reach of children
  • Do not use after the expiry date printed on the bottle or carton
  • Do not dispose of medicines via wastewater or household waste — return unused product to your pharmacy

Frequently Asked Questions

Where can I buy Polytar Scalp Shampoo online in the UK?

You can buy Polytar Scalp Shampoo directly from Cured Pharmacy, a GPhC-registered UK online pharmacy. It is available without a prescription as an over-the-counter medicine, so no GP visit is required. Simply add it to your basket and it will be dispatched to your door.

How does Polytar Scalp Shampoo work in the body?

Polytar Scalp Shampoo works topically on the scalp rather than systemically. Its active ingredient, coal tar solution 4%, slows down the overproduction of skin cells, reduces inflammation, and relieves itching. It also has mild antifungal properties that may help address the yeast component of dandruff and seborrhoeic dermatitis.

How do I use Polytar Scalp Shampoo step by step?

Using it correctly is straightforward. Follow these steps:

  1. Wet hair and scalp thoroughly
  2. Apply a generous amount to the scalp
  3. Massage in gently and leave for 3–5 minutes
  4. Rinse thoroughly and repeat if needed

Avoid contact with eyes. Use 2–3 times per week for best results.

How often should I use Polytar Scalp Shampoo each week?

The recommended frequency is two to three times per week for active scalp conditions such as psoriasis or dandruff. Once symptoms improve, you may be able to reduce use to once weekly as a maintenance wash. Always follow the guidance on the pack or as advised by your pharmacist.

What are the side effects of Polytar Scalp Shampoo and how do I manage them?

The most common side effects include mild scalp irritation, temporary redness, and slight dryness of the hair. Coal tar can also increase your scalp's sensitivity to sunlight, so wearing a hat outdoors after use is sensible. If you experience severe irritation, blistering, or signs of an allergic reaction, stop use immediately and speak to a pharmacist or GP.

Is Polytar Scalp Shampoo suitable for children?

Polytar Scalp Shampoo is suitable for adults and children aged 12 and over. It should not be used in children under 12 without specific medical advice from a GP or dermatologist. If your child has scalp psoriasis or severe dandruff, speak to your doctor before using any medicated shampoo.

Can I use Polytar Scalp Shampoo if I am pregnant or breastfeeding?

If you are pregnant or breastfeeding, you should speak to your doctor or pharmacist before using Polytar Scalp Shampoo. The safety of coal tar during pregnancy has not been fully established, and a healthcare professional can help you weigh up the risks and benefits. Do not self-treat without seeking advice first.

Will Polytar Scalp Shampoo discolour my hair?

Coal tar shampoos can occasionally cause temporary discolouration, particularly in light-coloured, blonde, grey, or chemically bleached hair. This is a known cosmetic effect rather than a harmful one. If you are concerned, speak to your pharmacist about whether an alternative medicated shampoo might be more suitable for your hair type.

How long does it take for Polytar Scalp Shampoo to work?

Most people begin to notice an improvement in scalp flaking and itching within two to four weeks of regular use. Psoriasis in particular is a chronic condition, so consistent use over time tends to produce the best results. If you see no improvement after four weeks, consult your GP or pharmacist for further assessment.

How long can you use Polytar Scalp Shampoo for?

Polytar Scalp Shampoo can be used for extended periods as part of an ongoing scalp management routine, particularly for chronic conditions like psoriasis. However, if your symptoms worsen or do not improve after four weeks of regular use, you should seek medical advice. Long-term use should ideally be reviewed periodically by a pharmacist or GP.

What are the best alternatives to Polytar Scalp Shampoo?

Alternatives include other coal tar shampoos such as T/Gel (neutrogena), or antifungal shampoos containing ketoconazole (e.g. Nizoral) for dandruff with a fungal component. Selenium sulphide shampoos are another option for seborrhoeic dermatitis. Your pharmacist can help you choose the most appropriate product based on your specific scalp condition. You can also explore our hair care collection for a broader range of options.

Can Polytar Scalp Shampoo be used on the body as well as the scalp?

Polytar Scalp Shampoo is specifically formulated for use on the scalp. While coal tar preparations are used for body psoriasis and eczema, you should use products specifically designed for body application rather than repurposing a scalp shampoo. Speak to your pharmacist about appropriate body-area coal tar treatments if needed.

Does Polytar Scalp Shampoo interact with other medicines?

No significant systemic drug interactions are known for topical coal tar at the concentration found in Polytar Scalp Shampoo. However, you should avoid using it alongside other photosensitising topical agents on the same area. Always inform your pharmacist of any other medicines or topical treatments you are using, just to be safe.

What happens if I accidentally get Polytar Scalp Shampoo in my eyes?

If Polytar Scalp Shampoo comes into contact with your eyes, rinse immediately and thoroughly with plenty of clean, lukewarm water. Do not rub your eyes. If irritation persists after rinsing, seek medical advice promptly. To prevent this, tilt your head back when rinsing and keep your eyes closed during application.

What is the latest research on coal tar shampoos for scalp psoriasis?

Coal tar remains a recognised and recommended treatment for scalp psoriasis in UK clinical guidelines, including those from the NHS and NICE. Research continues to support its anti-proliferative and anti-inflammatory properties for chronic scalp conditions. While newer targeted therapies exist for moderate-to-severe psoriasis, coal tar shampoos remain a practical and accessible first-line OTC option. You can also explore our skin care range for related products.

How Should You Use Polytar Scalp Shampoo?

Using Polytar Scalp Shampoo correctly is essential to getting the most from your treatment. It's a medicated product, not a regular shampoo, so the application method matters. Always read the patient information leaflet supplied with the product before use.

Follow these steps each time you use it:

What Is the Correct Dose of Polytar Scalp Shampoo?

There is no fixed measured dose for this shampoo — you apply enough to work into a lather across the scalp. The key variable is frequency of use, which depends on your condition and its severity. The table below summarises recommended usage by indication and age group.

When Is the Best Time to Use Polytar Scalp Shampoo?

There is no strict time of day requirement for using Polytar Scalp Shampoo. However, because coal tar can temporarily increase your scalp's sensitivity to sunlight, many people prefer to use it in the evening or at night. This reduces the risk of sun exposure to the treated scalp immediately after washing.

If you do use it in the morning before going outdoors, protect your scalp with a hat or appropriate head covering, particularly in sunny weather. Consistency matters more than timing — try to use it on the same days each week to build a routine.

How Long Can You Use Polytar Scalp Shampoo For?

Polytar Scalp Shampoo can be used as part of a long-term scalp management routine, particularly for chronic conditions like psoriasis. If you see no improvement after four weeks of regular use, stop and consult your pharmacist or GP, as you may need a different treatment or a prescription-strength option.

For conditions that respond well, many people use it on an ongoing basis, reducing frequency as symptoms improve. Periodic review with a healthcare professional is sensible for long-term users.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Polytar Scalp Shampoo?

Most people tolerate Polytar Scalp Shampoo well, particularly after the first few uses. The most frequently reported side effects are mild and localised to the scalp. They tend to settle as your skin adjusts to the coal tar.

  • Mild scalp irritation or stinging, especially on first use
  • Temporary redness of the scalp
  • Slight dryness of the scalp or hair shaft
  • Temporary discolouration of light-coloured, grey, or chemically treated hair

What Are the Less Common Side Effects of Polytar Scalp Shampoo?

Less commonly, some people experience side effects that require a little more attention. These are not dangerous in most cases, but they do warrant action if they occur.

  • Photosensitivity — increased sensitivity of the scalp to sunlight after use
  • Folliculitis — inflammation or infection of the hair follicles, presenting as small red bumps or pustules on the scalp
  • Allergic contact dermatitis — worsening redness, swelling, itching, or blistering that suggests a reaction to one of the ingredients

If you develop folliculitis or signs of an allergic reaction, stop using the shampoo immediately and seek advice from your pharmacist or GP. Do not continue use if your scalp condition is worsening rather than improving.

What Are the Serious Side Effects of Polytar Scalp Shampoo?

Serious side effects from topical coal tar at this concentration are rare. However, you should be aware that coal tar is classified as a potential carcinogen in occupational settings at high concentrations. At the levels used in medicated shampoos, the risk is considered very low for normal consumer use. If you have a personal or family history of skin cancer, discuss use with your GP before starting treatment.

Seek urgent medical attention if you experience any signs of a severe allergic reaction, including facial swelling, difficulty breathing, or widespread skin blistering.

What Should You Do If You Experience Side Effects of Polytar Scalp Shampoo?

For mild side effects such as temporary irritation or dryness, you can usually continue use and allow your scalp time to adjust. Reducing frequency from three times per week to twice per week may also help. For photosensitivity, protect your scalp from direct sunlight after use by wearing a hat.

If side effects are moderate or worsening, stop use and speak to your pharmacist. They can advise whether to continue, switch to an alternative, or refer you to your GP. You can report side effects directly to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk.

Can Polytar Scalp Shampoo Interact With Other Medicines?

No clinically significant systemic drug interactions are known for coal tar solution at the concentration used in Polytar Scalp Shampoo, as absorption through the scalp is minimal. However, you should avoid using it at the same time as other photosensitising topical agents on the scalp, as this could increase the risk of sun-related skin reactions. Always tell your pharmacist about any other topical treatments you are using on your scalp or skin.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
